To all whom 'it may concern:

Be it known that I, FRANK H. SEIDEL, a citizen vof the United States, residing at Harvey, in the county of Cook and State of Illinois, have invented a certain new and useful Multiple Mold, of which the following is a description.

My invention relates to a mold ada ted for casting large numbers of similar artic es with the least possible expense 'of time and labor both in the casting and the iinishing of the product.

The object of my invention is to provide a simple, serviceable, and convenient device of the kind described, and one arranged to release and discharge the articles from the mold as soon as possible after the casting operation by the mere opening or separating of the mold parts.

To this end my invention consists in the novel construction, arrangement, and combination of parts herein shown and. described, particularly pointed out in the claims.

In the accompanying' drawings, wherein like or similar reference characters indicate like or corresponding parte; Figure 1 is an end elevation of my device. Fig. 2 is a section taken substantially on line 2-2 of Fig. 8. Fig. 3 is a section taken substantially on line 3-3 of Fig. 1; and Fig. Li is a plan view of my device.

In the form shown in the drawings, my mold is adapted for casting sash weights, and comprises two substantially duplicate mold members 1 and 2 provided with recesses 3 3 As shown each member is chambered or hollow and provided With an inlet 4 and outlet 5-so that water or other suitable cooling i'luid'may be permitted to iiow through the member to control its temperature when in use.

The recesses 3-3 may be of any desired form, size, or arrangement.

groove or channel extending transversely of the mold member, with the lower end of each recess closed and so arranged that when the f members are in casting relation to each other a recess in one mold member will coperate with a recessin the opposite mold member to ,form a cylindrical o ening extending from As shown each *y recess conslsts merely of a semi-cylindrical provided with a projection 7 to form the.

opening for the receptionof the sash cord...

The closure 6 may be secured in position in any suitable manner. In the form shown each clbsure is adjustably positioned in its particular recess 3 and secured in place by means of a cap-screw 8 for which a lurality of threaded openings 949 are provi ed in the back ofthe recess 3 so that the closure 6 may ber adjusted longitudinally of the recess to control the length of the WeiA ht to be cast.

Any suitable means may e rovided to control thevrelative position of t e members 1 `and 2. As shown the member 1 is rigidly secured in any desired manner to a base l1() as for example by the set-screws 11. The base 10 is preferably of suitable length to eX- tend beyondv the vside of the member 2 when the same is in casting position and is there provided with a suitable bearing 12. A shaft 14 or equivalent means is' rotatably mounted in the bearings 12 upon the member 10 and provided at each end with an arm 15 keyed or otherwise rigidly secured thereto. The free end of the arm 15 is pivotally connected by a link 16 or other suitable means to the central portion of the member 2. The link 16 is provided with a sleeve-nut 17 or other suitable adjusting means intermediate its ends so that the relative positions of the opposite ends of the member 2 may be controlled as desired to equalize the pressure between the mold members. A lever 1S or other y convenient means is provided at a suitable point upon the shaft 14 for rotating the same and controlling the position of the member 2. y

In the form shown a suitable s ring actuatedl pawl 19 is provided upon t e, lever 18 adapted to engage a segment 20 to control the position of the lever.

Any suitable means may be provided 'for directing the metal or other material into the mold cavities 3-3. In the form shown a pair of hollow blocks 21-22 are provided upon the members 1 and 2 respectively with the proximate faces of the blocks 4suitably formed to provide La channel or runnerex-` tending along the top of the mold above the several recesses of. the mold, with a separate 5 opening 25 in the bottom of the runner communicatin with each mold cavity. Each.

of the bloc 21 and 22 are provided with an inlet 26 and an outlet 27- for conducting water or other cooling fluid'into, and away from, its interior.

he 'block members 21-22 may be secured to the members 1 and 2 in any suitable,-

manner, but as it frequently occurs that articles cast in a mold of this character tend to strongly adhere tothe walls of the m'old cavit or lthe runner block I prefer to mount- '25 The upper portion of the bracket 28 i preferably provided with a,pai'r of slots or jaws 29 .and'30 and a in or projection 31 and v32 is provided upon t e blocks 21 and 2 2 re- -spectively extending into the slots and so positioned that when the member 2 is moved to close the mold, that is, to bring its face in contact with the member 1 the pin 32 will be engaged by one wall of the respective jaw slots 29 to hold the face of the block 22 substantially even with the face of the member 2., As the member 2 moves toward the blot-ig 21 the face of the member 22 will engage the member 21 and carry the same into proper casting position when the mold is 40 closed.

In opening the-mold in casethe casing adheres to the-walls of the member 1 or block 21 the member 2 and block 22 will move away from the casting until the end of the slot 30 engages the in.31 upon the block 21 drawing it forward u on the member 1 and releasing the casting om the recesses 3 3. This movement also detaches the runner from its engagement with the block 21 permitting the 50' castings to fall through the space between the members leaving the mold entirely clear for the next casting operation.A

. 2 or block 22 a slight movement of the block 22 upon the member 2 usually entirely detaches the'same substantially as above described.

I C The operation of my device is very simple and rapid permittin very largequantities of A80 sash weights or simi arv articles to be formed with the least possible amount of labor and The molds being Aalways substantially ready to receive the molten metal or 4 other material of which the casting is to be @de sul If preferred suitable means in additionto the member 10 may be provided near the ends ofmy mold members to assist in maintaining the same in their proper relative positions, lAs shown a suita lerectangular bar 35 is rigidly attached at each end of the member 2 extending substantially arallel to the guiding face of the part 10. lPhe free end of the bar 35 is slidablyengaged in a bearing '36 rigidly attached to the end of the member 1 7 5 Y for this purpose.

' While in he foregoin lspecification I have described theparticular orm of mold adapted for use in casting sash weights it isobvious that a reat variety of articles may be formed 8o s of this character and as any amount of finish may be imparted to the moldefaces desired the castings produced may have an extremely smooth surface requiring very' little or no labor in inishing the same.v Itis also obvious that immaterial modiiications may be made in my device without departing' from the spirit of my invention, hence I do not wish to be understood as limiting myself to the exact form and construction shown. What I claim as new, and desire to secure by Letters Patent is 1. A mold, comprising two similar. relatively movable members, each rovided with recesses in their proximate faces adapted 95 jointly to serve as mold cavities, guiding means connecting said members, and mechanisml for controlling the movements and relative positions of the members, in combination with a pair of .blocks 4loosely mounted 100 uponsaid members jointly Aforming a runner for directing a uid into said mold cavities.

2.
